[Abstract]
Gansu is one of the main producing regions for sunflowers which provides ideal basis and suitable natural condition for sunflower production. To provide superior, high yield and disease-resistant cultivar in sunflowers, and to improve yields, quality of sunflowers as well as the household income of farmers, a new edible sunflower cultivar Jiukui 130 werebred by Jiuquan Academy of Agricultural Sciences through years' selection using cross breeding(sterile line XF118A as female parent and restorer line XF6013C as male parent). Data from regional trial with multiple sites carried out in 2018 and 2019 showed that average yield of Jiukui 130 (data from 10 sites in 2 years) was 4 248.0 kg/ha, which was 11.80% higher compared with the yield of control, JK601. Mean data in growth period, plant height, blade number, diameter of the sunflower head, seed setting rate, kernel rate, seed weight of individual head, 100-seed weight and seed length were 119 d, 200 to 220 cm, 30 to 32 blades, 24.6 cm, 90.2%, 52%, 178.4 g, 18.5 g and 2.46 cm, respectively. It is highly resistant to yellow wilt disease, black spot disease and brown spot disease, and is moderately resistant to sclerotium disease. This new cultivar is recommended in Hexi Corridor region, central region of Gansu and other regions with similar environment for spring sowing.
